Learn The Color Gamut Of The LCD Monitor

- Jun 27, 2018 -

The color gamut defines a more specific range within the color range (ie, the visible spectrum) that the human eye can recognize. Color imaging devices include a variety of devices, such as digital cameras, scanners, monitors, and printers. Because the color ranges that they can reproduce are different, the concept of the color gamut is used to distinguish these differences and to coordinate the common use among devices. colour.

There are several ways to express the color gamut (through charts), but the common method for displaying products is the xy chromaticity diagram of the XYZ color system developed by the International Commission on Illumination (CIE). In the xy chromaticity diagram, the colors in the visible range are represented numerically and marked as color coordinates. In the following xy chromaticity diagram, an inverted "U" shaped area surrounded by dashed lines represents the range of colors that human l can see with the naked eye.

A variety of standards can manage the color gamut. The three standards that are often used on personal computers are sRGB, Adobe RGB, and NTSC. The gamut defined by each standard appears as a triangle on the xy chromaticity diagram. These triangles show the peak RGB coordinates and connect them with straight lines. The larger the area of the triangle, the more colors the standard can display. For liquid crystal displays, this means that the larger the triangle of the color gamut that a product is compatible with, the greater the range of colors restored on the screen.
